In Response To: historical position 1 (Matt Cohn-Geier)

Blue has 15 ways to hit on the ace point after playing 7/5. He's got more after B/20

Right! Thanks for the correction. So, Blue has a real chance of hitting a second checker after playing bar/20.

And here's a rollout at 17-away all. Gnubg wins more games and more gammons with bar/20.

The score (after 0 games) is: White 0, Me7 0 (match to 17 points)

Move number 5: Me7 to play 32

White	79
Me7	91
